I do my best to measure some of his behavior against how I was when I was his age. Some of the stuff I did was over the top in comparison, I was just lucky. I'm very happy he is not doing drugs and drinking.
He does not like college, living at home or my rules. He has been given a few options. Go to college, get a job and pay rent, just get out, or join the service. We're pushing college on him and paying for everything minus his gas money and entertainment fund.
One of my biggest regrets ever has been video games. Complete time sucking, nonsense! I traded a super rusty 240z that I paid $80 for a $400 game system. Funny my dad used to get on me when I was kid too about wasting quarters, but If you don't have money to play, you don't play.
